Detailed Description
All the modes in the present disclosure are merely examples, and are not intended to exclude other examples from the present disclosure, and are not intended to limit the technical scope of the invention described in the claims.
Some descriptions of combinations of the respective modes in the present disclosure may be omitted. The omission is intended to simplify the description, is not intended to exclude the disclosure of the present invention, and is not intended to limit the technical scope of the invention described in the claims. All combinations of the various aspects of the disclosure with each other, whether or not omitted, are expressly, implicitly or inherently included in the disclosure. That is, all combinations of the respective modes in the present disclosure can be directly and clearly derived from the present disclosure, regardless of the omission.
For example, as shown in fig. 1 to 12, an antenna according to one embodiment of the present disclosure may include an open conductor portion 101 and an intra-annular conductor portion 102, the open conductor portion 101 may be present outside the region 103 and outside the opening 104 of the portion along the outline of the region 103, the intra-annular conductor portion 102 may be present inside the region 103, may be continuous with one of the portions of the open conductor portion 101 across the opening 104, or may be at least partially bent along the open conductor portion 101.
For example, region 103 may be surrounded by split ring conductor portion 101 and opening 104.
For example, the region 103 may have an arbitrary shape, a polygonal shape such as a square or rectangle, or a circular or elliptical shape.
For example, split ring conductor portion 101 may be formed of a metal plate.
For example, the split ring conductor 101 may have any shape, and may have a substantially C-shape along a square ring, or may have a shape along various other ring shapes such as a circular ring, an elliptical ring, and a raceway ring.
For example, the split ring conductor portion 101 may include an auxiliary conductor 1011 at a portion thereof spaced apart from the opening 104. Auxiliary conductor 1011 may be provided on the same layer as split ring conductor 101 or may be provided on a different layer.
For example, the opening 104 may be filled with resin or the like without being filled with any substance.
For example, the opening 104 may have any shape, such as a straight line, a curved line, and a broken line.
For example, the opening 104 may be a serpentine shape. The term meander shape encompasses concepts known as serpentine shapes, comb-tooth shapes, shapes based on interdigitated structures, and the like. For example, the meandering shape is formed by a combination of straight lines, curved lines, broken lines, and the like.
For example, the in-ring conductor part 102 may be formed of a metal plate.
For example, the intra-ring conductor portion 102 may be disposed in the same layer as the split-ring conductor portion 101. However, the portion of the split ring conductor portion 101 other than the portion along the intra-ring conductor portion 102 may be provided in a layer different from the layer in which the intra-ring conductor portion 102 is present.
For example, the intra-ring conductor portion 102 and the split ring conductor portion 101 can be formed by cutting out from a single conductor plate with a laser or the like.
The antenna according to one aspect of the present invention can be considered to include two resonant circuits, for example.
The first resonant circuit can be regarded as being constituted by a capacitance generated in the opening 104 by supplying an RF (Radio Frequency) signal and an inductance generated in the open conductor portion 101. It can be seen that a first resonance frequency is generated by the first resonance circuit.
The second resonant circuit can be regarded as being constituted by, for example, a capacitance generated in the opening 104 by supplying an RF signal, an inductance generated in the intra-ring conductor portion 102, a capacitance generated between the split-ring conductor portion 101 and a portion of the intra-ring conductor portion 102 along the split-ring conductor portion 101, and an inductance generated in a portion of the split-ring conductor portion 101 other than the portion along the intra-ring conductor portion 102. It can be seen that a second resonance frequency is generated by the second resonance circuit.
As can be seen from the above, the resonant frequency of the first resonant circuit and the resonant frequency of the second resonant circuit can be regarded as different from each other.
If the resonant frequency of the first resonant circuit is set to be distant from the resonant frequency of the second resonant circuit, the antenna is a multiband antenna. If the resonance frequency of the first resonance circuit is brought close to the resonance frequency of the second resonance circuit, the antenna is a wide-band antenna. For example, when the resonance frequency of the second resonance circuit is higher than the resonance frequency of the first resonance circuit, the resonance frequency of the first resonance circuit may be brought close to the resonance frequency of the second resonance circuit by adjusting the resonance frequency of the second resonance circuit to be low. In order to adjust the resonance frequency of the second resonant circuit to be low, for example, the following adjustment is performed: making the length of the in-loop conductor part 102 longer; narrowing the width between split ring conductor part 101 and the portion of split ring conductor part 102 along split ring conductor part 101; a chip capacitor is provided between the split ring conductor part 101 and a part of the intra-ring conductor part 102 along the split ring conductor part 101; or the region between the split ring conductor portion 101 and the portion of the intra-ring conductor portion 102 along the split ring conductor portion 101 is formed in a meandering shape.
As described above, according to one aspect of the present disclosure, for example, an antenna can be provided in which the resonance frequency is multi-banded or wideband while maintaining the advantages of a split ring (small size and low manufacturing cost).
According to one aspect of the present disclosure, for example, as shown in fig. 13, the bandwidth in which the return loss is equal to or less than the threshold value a may be wider than the case where the resonance frequency is single. The threshold a is, for example, -10dB, but is not limited thereto, and when the return loss is equal to or less than the threshold a, the antenna may be operated sufficiently.
The antenna according to one embodiment of the present disclosure may be formed as a member to be mounted on the substrate 2 or the like later.
The antenna of one embodiment disclosed in the present invention may be formed directly on the substrate 2, for example.
The antenna according to one embodiment of the present invention may protrude from the substrate 2, for example.
The antenna according to one embodiment of the present disclosure may be disposed substantially perpendicular to the substrate 2, for example.
For example, as shown in fig. 1 to 12, in the antenna according to one embodiment of the present disclosure, the width between split-ring conductor portion 101 and the portion of intra-ring conductor portion 102 that extends along split-ring conductor portion 101 may be narrower than the width between split-ring conductor portion 101 and the portion of intra-ring conductor portion 102 that extends beyond split-ring conductor portion 101.
For example, as shown in fig. 1 to 12, the portion of the open conductor part 101 and the portion of the intra-loop conductor part 102 along the open conductor part 101 of the antenna according to one embodiment of the present disclosure may be close to each other to have a capacitance contributing to resonance.
As described above, in one aspect of the present disclosure, for example, it can be considered that the second resonant circuit is formed by a capacitance generated between the open conductor portion 101 and a portion of the intra-ring conductor portion 102 along the open conductor portion 101 by supplying an RF signal.
For example, in an antenna according to one aspect of the present disclosure (for example, the antenna 1A and its modified examples), as shown in fig. 14 to 27, the in-loop conductor section 102 may be fed with power by connection of the power feed line 105 or wirelessly fed with power.
For example, the feed line 105 may be connected to any portion of the intra-loop conductor portion 102, and the RF circuit and the antenna according to one embodiment of the present disclosure can be impedance-matched by adjusting the connection portion.
For example, the power supply line 105 may be provided in a layer different from the layer in which the in-ring conductor section 102 exists, and connected to the in-ring conductor section 102 via the through hole 3.
For example, the feeder line 105 may be provided in the same layer as the layer in which the intra-ring conductor part 102 is present, and may extend in the region 103, or may extend along a gap provided in the open-ring conductor part 101 or the substrate.
For example, the feeder line 105 may be formed of an isopotential line of a transmission line or a metal plate.
For example, the metal plate portions of the in-ring conductor portion 102 and the feeder line 105 may be formed by cutting out from one conductor plate with a laser or the like.
Wireless power supply to the in-loop conductor section 102 can be realized by, for example, an EM (Electro-Magnetic) coupling section 106 to which a power supply line 105 is connected.
For example, the EM coupling section 106 may perform EM coupling with any part of the in-loop conductor section 102, and the impedance of the RF circuit and the antenna according to one embodiment disclosed in the present invention can be matched by adjusting the position of the EM coupling.
For example, the EM coupling portion 106 may be disposed at a different layer than the layer in which the in-loop conductor portion 102 is present.
For example, the EM coupling section 106 may be provided on the same layer as the layer in which the intra-ring conductor section 102 is provided, and the feed line 105 connected to the EM coupling section 106 may extend in the region 103 or may extend along a gap provided in the split ring conductor section 101 or the substrate.
For example, EM coupling 106 may be formed from a metal plate.
For example, the intra-ring conductor section 102 and the EM coupling section 106 may be formed by cutting out from a single conductor plate with a laser or the like.
For example, the metal plate portions of the EM coupling portion 106 and the feeder line 105 may be formed by cutting out from one conductive plate with a laser or the like.
As described above, according to one aspect of the present disclosure, for example, the second resonant circuit is directly supplied with power, and the first resonant circuit is supplied with power via the in-loop conductor section 102. Therefore, according to one aspect of the present disclosure, for example, a favorable antenna characteristic is obtained compared to a case where feeding or wireless feeding is performed by connection of a feeder line not to the in-loop conductor part 102 but to the open-loop conductor part 101.
For example, in an antenna according to one aspect of the present disclosure (for example, the antenna 1B and its modified example), as shown in fig. 28 and 29, the open loop conductor part 101 may be fed with power by connection of the power feed line 107 or wirelessly fed with power.
For example, feed line 107 may be connected to any portion of open conductor portion 101, and by adjusting the connection portion, the impedance of the RF circuit and the antenna according to one embodiment of the present disclosure can be matched.
For example, power supply line 107 may be provided in a layer different from the layer in which split conductor portion 101 is present, and may be connected to split conductor portion 101 via through-hole 3. For example, power feed line 107 may be provided in the same layer as that in which split conductor part 101 is present, and may extend in region 103, or may extend along a gap provided in split conductor part 101 or the substrate.
For example, the feeder line 107 may be formed of an isopotential line such as a transmission line, or may be formed of a metal plate. For example, the metal plate portions of the open conductor portion 101 and the power supply line 107 may be formed by cutting out from one conductor plate with a laser or the like.
Wireless power supply to the open loop conductor portion 101 can be realized by, for example, an EM (Electro-Magnetic) coupling portion 108 to which the power feed line 107 is connected.
For example, EM coupling section 108 may be EM coupled to any part of split ring conductor section 101, and by adjusting the portion of EM coupling, the impedance of the RF circuit and the antenna according to one embodiment disclosed in the present invention can be matched.
For example, EM coupling 108 may be disposed on a different layer than the layer in which split ring conductor portion 101 is present.
For example, EM coupling section 108 may be provided on the same layer as that on which split conductor section 101 is provided, and feed line 107 connected to EM coupling section 108 may extend in region 103 or may extend along a gap provided in split conductor section 101 or the substrate.
For example, the EM coupling 108 may be formed from a metal plate.
For example, the split ring conductor portion 101 and the EM coupling portion 108 can be formed by cutting out from a single conductor plate with a laser or the like.
For example, the metal plate portions of the EM coupling portion 108 and the feeder line 107 may be formed by cutting out from one conductive plate with a laser or the like.
As mentioned above, according to one mode of the present disclosure, for example, the first resonant circuit is also directly powered. Thus, according to one aspect of the present disclosure, for example, finer tuning is enabled.
For example, in an antenna according to one aspect of the present disclosure (for example, the antenna 1A, 1B, 1C and the modified examples thereof), as shown in fig. 30 and 31, the region 103 may be substantially a quadrangle, the opening 104 may be present in the vicinity of a corner (vertex) of the region 103, the intra-annular conductor portion 102 may be bent once so as to follow the open-ring conductor portion 101 when viewed from a portion continuous with the open-ring conductor portion 101, and a portion between the first bent portion and the terminal end may be bent once.
For example, in the antenna according to one aspect of the present disclosure (for example, the antenna 1A, 1B, 1C and the modified examples thereof), as shown in fig. 30 and 31, the width between the portion between the second bent portion and the terminal and the open conductor portion 101 may be narrower than the width between the portion between the two bent portions of the open conductor portion 102 and the open conductor portion 101, as viewed from a portion of the intra-ring conductor portion 102 continuous with the open conductor portion 101.
In the above-described aspect of the present invention, for example, good antenna characteristics are obtained particularly in a wide frequency band.
For example, in the antenna according to one aspect of the present disclosure (for example, the antennas 1A, 1B, 1C, 1D and the modifications thereof), as shown in fig. 32 to 34, the in-loop conductor portion 109 may be provided, the in-loop conductor portion 102 may be present outside the region 110 and outside the opening 111 of the portion along the outline of the region 110, the in-loop conductor portion 109 may be present inside the region 110, may be continuous with one of the portions of the in-loop conductor portion 102 across the opening 111, or may be at least partially bent along the in-loop conductor portion 102.
For example, the region 110 may be surrounded by the in-loop conductor portion 102 and the opening 111.
For example, the region 110 may have any shape, may have a polygonal shape such as a square or rectangle, or may have a shape such as a circle or ellipse.
For example, the opening 111 may be filled with resin or the like without being filled with any substance.
For example, the opening 111 may have any shape, such as a straight line, a curved line, and a broken line.
For example, the opening 111 may also be a meandering shape.
For example, the in-ring conductor part 109 may be formed of a metal plate.
For example, the in-loop conductor portion 109 may be disposed in the same layer as the in-loop conductor portion 102. However, the portion of the in-ring conductor section 102 other than the portion along the in-ring conductor section 109 may be provided in a layer different from the layer in which the in-ring conductor section 109 is present.
For example, the in-ring conductor portion 109 and the in-ring conductor portion 102 can be formed by cutting out from one conductive plate with a laser or the like.
For example, the in-loop conductor portion 109 may be supplied with power by connection of a power supply line or wirelessly supplied with power.
The antenna according to the above-described aspect of the present invention may be considered to further include a third resonant circuit, for example.
The third resonant circuit can be regarded as being constituted by, for example, a capacitance generated in the opening 111 by the RF signal being supplied, an inductance generated in the in-loop conductor portion 109, a capacitance generated between the in-loop conductor portion 102 and a portion of the in-loop conductor portion 109 along the in-loop conductor portion 102, and an inductance generated in a portion of the in-loop conductor portion 102 other than the portion along the in-loop conductor portion 109.
As described above, according to one aspect of the present disclosure, for example, an antenna can be provided in which the resonance frequency is multi-banded or wideband while maintaining the advantages of a split ring (small size and low manufacturing cost).
In addition, according to one aspect of the present disclosure, for example, it is possible to provide an antenna in which an intra-conductor portion is formed similarly in the region 103, the region 110, the region 112, and the region …, thereby further increasing the resonance frequency in a multi-band or a wide-band while maintaining the advantages of the split resonance ring (small size and low manufacturing cost).
For example, the communication device according to one aspect of the present disclosure may include the antenna according to one aspect of the present disclosure (e.g., the antennas 1A, 1B, 1C, 1D, and 1E and their modifications).
In the above-described aspect of the present invention, for example, a small-sized and high-performance communication device can be provided.
The present invention has been described above by way of illustrative examples of the above embodiments. However, the present invention is not limited to the above embodiments. That is, the present invention can be applied in various ways understood by those skilled in the art within the scope of the present invention.
